In bread wrapping, machines" of. the type" disclosed in Patents Nos; 'l,977,307 andf'2;022,911,

issued October '16, 1934, and'December 3', 193-5,

respectively,v the machines are designed for Wrapping the conventional oblong. bread loaf.

It is. an object of this: invention to provide-a.

meansji'n the form of an attachment whereby the machines disclosed in the patents, supra, may be converted in amanner whereby round loaves, such as round loaves of'rye bread or the like, may be easily and quickly wrapped in a heat-sealed wrapper.

Another object of this" invention is to provide an attachment of. this kind which can be easily and quickly applied without changing'thje present parts. of the machine, so that the same machine can. beused for, wrapping, either round. or'oblong loaves ofbr'eadl. 1

A further object of this: invention'is' to. pro= vide an attachmentfor wrapping round leaves which will. hold the wrapper snugly about the loaf'until' the wrapper is sealed.

With the above and other objects in view, my

invention consists in the arrangement, combinationand details of construction disclosed in the drawings and specification, and then more particularly pointed outLin the-appended claims.

In the. drawings:

Figure 1 is a fragmentary vertical sectionof a bread wrapping machine having an attachment mounted thereon constructed according to an embodiment of this invention.

Figure 2 is a fragmentary sectional view taken on the line 22 of Figure 1.

Figure 3 is a fragmentary sectional view taken on the line 3-3 of Figure 1.

Figure 4 is a fragmentary sectional view taken on the line 4-4 of Figure 3.

Figure 5 is a fragmentary sectional view taken on the line 5-5 of Figure 4.

Figure 6 is a bottom plan view of the circular bread wrapper holding member.

Figure 7 is an exploded bottom plan of the two substantially semi-circular wrapper holding members.

Referring to the drawings the numeral 10 designates generally a conventional bread wrapping machine similar to that disclosed in Patents Numbered 1,977,307 and 2,022,911, supra. The machine disclosed in the above mentioned patents embodies an elevator II which is vertically movable to raise a bread loaf B upwardly to a position for contact by means of a pair of reclaims; (cra 2 7.

Iii-order to provide a means whereb'yar'ou'nd bread "loaf may be neatly wrapped in the same machine as hereinbefore I described, I have provided a-wrapperpressing ring 25Iwhich has extending upwardly therefromfa pluralityof upwardly convergent radial arms 26.v The arms 26 are secured to a disc shaped plate 21, and plate 21 is secured by fastening means 28 to a rock lever 29. The rock lever 29 forms a part of the conventional bread wrapping machine.

The ring 25 is of such size that it will encircle the upper portion of the round loaf B as clearly shown in Figures 4 and 5.

The wrapper engaging about the bread loaf B is also snugly pressed against the loaf by means of a pair of substantially semi-circular presser bars 30 and 3|. Presser bar 30 is secured to the pusher plate 22 by forming an upwardly projecting arm 32 which has secured thereto a hori- The plate 33 is adapted to be secured by fastening means 34 to the forward side of pusher plate 22. The semicircular pressing member St has extending upwardly therefrom an arm 35' which has fixed thereto a plate or base member 36 secured by fastening means 31 to the inner side of plate 2|. The two semi-circular wrapper pressing members 30 and 3| contact with the loaf and the wrapper the rock lever 29. The two semi-circular presser members 30 and 3! are secured to the inner faces of the plates 2'! and 22. The ring 25 will smooth out the wrapper engaging about the upper portion of the bread loaf B; whereas, the semicircular presser members 30 and 3] will also smooth out the wrapper about the bread loaf B 5 adjacent the lower portion of the loaf; The machine will operate in the conventional manner after the wrapper pressing members engage the wrapper about the loaf so that the loaf will subsequently be moved forwardly over the bottom heater 24 and the side heaters 23. As the loaf is moved forwardly between the heaters 23 lever arm I3 will be. raised upwardlytodisengage the side presser members l2 and the presser member 3| from the loaf. The presser member 30 forms thepusher or ram which will move the loaf forwardly to a point between side conveyorsforming part of the machine it! whereupon the pull of the conveyors will pull the loaf B from beneath the circular presser member 25. e

The attachment hereinbefore' described will provide a means whereby the bread wrapping machine which has beendesigned for wrapping of oblong loaves may be also used for the wrapping of round loaves of bread.

What is claimed is:

1. An attachment for a bread loaf wrapping machine for round loaves, said machine having a supporting frame and a movable carriage, a pair of opposed arcuatewrapper presser plates engageableagainst the opposite sides of the loaf, and a lever having -an end overlying the top of the loaf secured to: said platesformoving the same, whereby round bread loaves may be wrapped by said machine, said attachment comprising a ring engageable about the upper'portion of the loaf, a plate above said ring, upwardly convergent arms fixed between said ring andsaid last-mentioned plate, meansconnecting said plate to said carriage for simultaneous movement therewith, a pair of substantially semi-circular edges of said presser plates, means carried by said bars for securing the latter to said carriage in confronting position relative to each other and at substantially right angles to said presser plates whereby said plates and said bars press the wrapper closely about said loaf, and means for moving said carriage linearly to shift said wrapped loaf.

2. In a bread-loaf wrapping machine having aframe, a, loaf. supporting elevator, Wrapper presser plates engageable against the opposite sides of the loaf and a lever overlying the top of the loaf connected to said plates. an attachment whereby round bread loaves may be wrapped by said machine, said attachment com- .7 prising. aring engageable about the upper portion of said loaf, means securing said ring to theretofor engagement over the top of said leaf, and a pair of arcuate bars, one of said bars being connected to said lever and movable with said plates, "said bars being disposed below said "ring to thereby press a wrapper about the loaf when saidloaf is raised by the elevator.

3; In a bread loaf wrapping machine having a frame, a loaf supporting elevator, wrapper presser plates engageable against the oppOsite sides of the loaf and a lever overlying the top of the loaf connected to saidplates, an attachment whereby round bread loaves may be wrapped by said. machine, said attachment comprising a ring, engageable about the upper portion of said loaf; means securing said ring to said frame in downwardly offset position relative thereto for engagement over the top of said loaf,.a pair of arcuate bars, one of. said bars being connected to said lever and movable withsaid plates, said bars being disposed below said ring to thereby press a wrapper about. the loaf ,when said loaf is raised by the elevator, the other'of said bars being linearly movable with said frame to move said loaf from said elevator after wrapping.
